KNIFE AND FORK CLEANER.

SPECIFICATION forming part of Letters Patent No. 722,174, dated March 3, 1903.

Application led October 2, 1902l Serial No. 125,702. (No model.)

driving mechanism for said rolls and whereby also disks for acting upon the tines of a fork and a small roll for acting uponthe stems and handles of forks and upon the handles of knives are effectively combined with the rolls which act upon the knife-blades.

In the accompanying drawings, YFigure 1 is a view, partlyin elevation and partlyin longitudinal section, of a knife and fork cleaner constructed in accordance with my invention. Fig. 2 is a transverse section on the line a a, Fig. 1; and Fig. 3 is a sectional plan view of part of the frame of the device on the line b l), Fig. 2.

The xed frame of the device has a base 1 for being secured to a table or bench, this base supporting a trough 2, which has at each end an upwardly-projecting wall 3,'slotted for the reception of the journals of upper and lower shafts t and 5 and also for the reception of intermediate journal-boxes 6 and upper journal-boxes 7, whereby said shafts are properly retained in their respective positions. The shafts 41 and 5 carry the upper and lower cleaning-rollers S and 9, respectively, these rollers being contained longitudinally between the end Walls 8 of the device and the lower roller 9 extending into the trough 2, so that a supply of water can be maintained in the trough for moistening the lower roller when such moistenin g of the same is required. The upper shaft 4 has at one end a spur-wheel 10, and the lower shaft has at the like end a spur-wheel 11, and both these spur-wheels mesh with an internal annular rack 12 on a flanged disk 13, which is mounted so as to be free to turn upon a stud Mathe latter projecting outwardly from a yoke 15, which is secured to or forms part of one of the end walls 3 of the iixed structure. The

disk 13 is provided with a projecting handle 16, whereby it may be readily turned, such turning movement effecting rotation of both of the cleaning-rollers 8 and 9 in the same di-` rection, as indicated, for instance, by the arrows in Figs. 1 and 2. The rollers therefore have no tendency to pull forward or push backward a knife-blade inserted between them, the movements of the knife being only such as are imparted to it by the attendant. Hence there is rapid and effective cleaning or polishing action upon both faces of the blade simultaneously,and 'the thorough cleaning or polishing of the blade is consequently eected in a short time.

That endV of the upper shaft 4 opposite to the end which carries the spur-wheel 10 projects beyond the fixed frame and is provided with a hub 17, from which project a series of disks 18, of emery or other desired cleaning or polishing material, whereby the tines of forks can be acted upon, and the lower shaft 5 projects in like manner for the reception of the small cleaning or polishing roller 19, which can be used for cleaning the stems and handles of forks or the handles of knives.

By mounting the supplementaryV cleaning or polishing rollers upon the projecting ends of the shafts which carry the main rollers 8 and V9 the same driving mechanism suiices for both and the number of parts is reduced to a minimum, the simplicity of construction thus attained correspondingly reducing the cost of the device.

Having thus described my invention, I claim and desire to secure by Letters Patent- The combination of the lixed frame, upper and lower shafts mounted therein and each carrying a cleaning-roller, a spur-wheel at one end of each of said shafts, a yoke projecting from the fixed frame and having a projecting'stud in the vertical plane passing through said upper and lower shafts, and a 9 THOMAS DAVIDSON, JR.
